## Early life and training
Mackenyu grew up in Los Angeles, where he appeared in a few films and television shows while in school and pursued a wide range of activities: horseback riding, Kyokushin Karate, gymnastics, water polo, and wrestling, along with music, learning piano at age ten and later saxophone and flute[1](https://www.imdb.com/name/nm5018289/). A Japanese profile describes him as skilled enough at [Kyokushin](https://www.edgepedia.org/kyokushin) karate to win a tournament in Los Angeles[6](https://news.livedoor.com/article/detail/12055286/).
At 15 he decided to become an actor after watching a film starring [Haruma Miura](https://www.edgepedia.org/haruma-miura), whom he later acted alongside in *Brave: Gunjyo Senki* (2021)[7](https://www.pep.ph/lifestyle/lifestyle/mackenyu-a5128-20230913). His first lead role came at 16 in *Take a Chance* (2015)[7](https://www.pep.ph/lifestyle/lifestyle/mackenyu-a5128-20230913).
## Career in Japan
His Japan-based career began in 2014[3](https://mackenyu.jp/biography/). Early credits include *Kamen Rider Drive: Surprise Future* (2015), in which he played Eiji Tomari[4](https://kamenrider.fandom.com/wiki/Mackenyu), and *Tadaima* (2015), for which he won Best Supporting Actor at the 2015 Asians On Film Festival[7](https://www.pep.ph/lifestyle/lifestyle/mackenyu-a5128-20230913).
**Chihayafuru and the Japan Academy award.** The role that made his name in Japan was Wataya Arata in the *Chihayafuru* trilogy released in 2016, which earned him the 40th Annual Japan Academy Newcomer of the Year Award in 2017[1](https://www.imdb.com/name/nm5018289/). *Chihayafuru Part I* holds a 71% critics score on Rotten Tomatoes, and he returned as Arata Wataya in *Chihayafuru Part 3* (2018)[8](https://www.rottentomatoes.com/celebrity/mackenyu).
Through the late 2010s he built a record of roles in adaptations of popular series: Okuyasu Nijimura in *JoJo's Bizarre Adventure: Diamond Is Unbreakable - Chapter 1* (2017), Naozumi Hiyama in *Over Drive* (2018), and the supporting role of Cadet Ryoichi in the Hollywood production *Pacific Rim: Uprising* (2018)[1](https://www.imdb.com/name/nm5018289/). He also voiced Haru in *NiNoKuni* (2019) and played Souta in *Tokyo Ghoul 'S'* (2019)[9](https://cinegraph.org/people/mackenyu/legacy).
**The 2021 pivot.** In 2021 he played the villain Enishi Yukishiro, the main antagonist of *[Rurouni Kenshin: The Final](https://www.edgepedia.org/rurouni-kenshin-the-final)*, and starred in *Brave: Gunjyo Senki* and *The Master Plan* (*Na mo Naki Sekai no End Roll*)[4](https://kamenrider.fandom.com/wiki/Mackenyu) • [9](https://cinegraph.org/people/mackenyu/legacy). That same year he left his agency Top Coat and suspended his activities in Japan, citing an intent to expand his career globally[4](https://kamenrider.fandom.com/wiki/Mackenyu).
## International breakthrough
The two 2023 releases that followed made him internationally known. In *[Knights of the Zodiac](https://www.edgepedia.org/knights-of-the-zodiac-film)* (*Saint Seiya: The Beginning*), an adaptation of Masami Kurumada's manga, he played the lead, Seiya, in his first Hollywood starring role[5](https://www.gqjapan.jp/article/20230427-mackenyu-arata-hype). On Rotten Tomatoes the film registers a 20% critics score against a 60% audience score[8](https://www.rottentomatoes.com/celebrity/mackenyu).
In 2021 he had been cast as Roronoa Zoro in Netflix's live-action *One Piece*; season 1 was released on August 31, 2023, covering the manga up to the end of the Arlong Park Saga[4](https://kamenrider.fandom.com/wiki/Mackenyu). The role drew on his martial arts background: he does his own stunts, and he brought the action team from the *Rurouni Kenshin* films to *One Piece*, saying season 2 has much more action and a deadlier Zoro[10](https://www.crunchyroll.com/news/interviews/2025/2/21/mackenyu-assassins-creed-one-piece-interview). Zoro has been his favorite character since childhood, and he told Gulf News that playing him initially felt frightening before becoming a dream come true[11](https://gulfnews.com/entertainment/exclusive-one-pieces-mackenyu-on-zoro-it-was-painful-in-season-one-1.500676622).
The series has continued. Season 2, *[One Piece](https://www.edgepedia.org/one-piece-2023-tv-series): Into the Grand Line*, premiered on March 10, 2026, covering the first half of the Alabasta Saga, and Mackenyu returns for a third season covering the latter half[4](https://kamenrider.fandom.com/wiki/Mackenyu). In the Whiskey Peak sequence of season 2, Zoro defeats a hundred bounty hunters; Mackenyu said the production counted every opponent because fans would[11](https://gulfnews.com/entertainment/exclusive-one-pieces-mackenyu-on-zoro-it-was-painful-in-season-one-1.500676622). He also voices Zoro in *LEGO One Piece* (2026)[12](https://www.tvguide.com/celebrities/mackenyu/credits/3030875215/).
Alongside *One Piece*, 2023 brought two Disney+ projects: *Dragons of Wonderhatch*, a mixed live-action and animation series in which he played Akuta, with episodes beginning December 20, 2023, and the drama *House of the Owl*, released in 2024, in which he played Ryu Ogami[1](https://www.imdb.com/name/nm5018289/) • [13](https://mackenyu.org/). In 2025 he voiced the shinobi Gennojo in both the English and Japanese versions of the video game *Assassin's Creed Shadows*[4](https://kamenrider.fandom.com/wiki/Mackenyu).
## Martial arts, action work, and reception
His Kyokushin karate background underpins the action roles that dominate his filmography, and he performs his own stunts[10](https://www.crunchyroll.com/news/interviews/2025/2/21/mackenyu-assassins-creed-one-piece-interview) • [6](https://news.livedoor.com/article/detail/12055286/). The three-sword style of Zoro, with a blade gripped in his teeth, remains uncomfortable two seasons in; he told Gulf News it was painful in season one and still is[11](https://gulfnews.com/entertainment/exclusive-one-pieces-mackenyu-on-zoro-it-was-painful-in-season-one-1.500676622).
On Rotten Tomatoes his highest-rated films are *JoJo's Bizarre Adventure: Diamond Is Unbreakable - Chapter 1* and *Rurouni Kenshin: Final Chapter Part I - The Final*, both at 100% with critics, while *Knights of the Zodiac* is his lowest at 20%[8](https://www.rottentomatoes.com/celebrity/mackenyu). A 2024 academic paper in the journal BASIS examined his career in manga and anime live-action adaptations as a case of cross-cultural narrative integration in cinema, describing him as a superstar in Japan whose Hollywood recognition was still developing[14](https://ejournal.upbatam.ac.id/index.php/basis/article/download/8722/3938).
He has also drawn industry attention off screen. Since 2018 he has served as the face of the Japanese men's grooming brand GATSBY[7](https://www.pep.ph/lifestyle/lifestyle/mackenyu-a5128-20230913), and in December 2023 he received the Global Groundbreaker for One Asia Award at the 21st annual Unforgettable Gala[13](https://mackenyu.org/). In 2026, [PC Gamer](https://www.edgepedia.org/pc-gamer) reported that Esquire Singapore had published an interview with him generated by AI chatbots fed from his earlier statements after his schedule prevented a real conversation, a piece that drew criticism from journalists[15](https://www.pcgamer.com/movies-tv/magazine-generates-fake-ai-interview-with-one-piece-actor-mackenyu/).
